Germ History Made Simple
Microbes are tiny organisms that cause diseases such as; strep throat, ear infections, and pneumonia in people. Microbes were first discovered in the late 1600s, but the idea that these tiny organisms could cause these diseases did not develop until the 1800's.

Scientist (Life Span)
Occupation Most Famous Contribution to Science Other Contributions to Science
Robert Hooke (1635-1703)
Scientist/ Inventor Made drawings of individual cells in plants. Made Microscopes to observe
microscopic things
Rudolf Carl Virchow (1821-1902)
German Doctor, anthropologist, etc.
Came up with a theory about cells. Founded medical fields of cellular pathology and comparative pathology.
Robert Koch (1843-1910)
Microbiologist
Discovered Mycobacterium tuberculosis Identified microbe that caused “Anthrax” which was killing thousands of cows.
Florence Nightingale (1820-1910)
Wartime Nurse
Discovered that improved sanitation would save more soldiers. Also helped with English feminism and theology.
Joseph Lister (1827-1910)
Medicine
Discovered carbolic acid’s antiseptic properties. Became the second man to operate on a brain tumor.
B.
All living things or organisms are made of cells and their products.
New cells are created by old cells dividing into two.
Cells are the basic building units of life.
C. Describe how the contributions of Louis Pasteur made foods and beverages safer for people and go on to explain how this revolutionary process continues in our lives today.
Louis Pasteur was most notably known for discovering the process of pasturazation, which is the process of making food not spoil and help it last longer and make it safer to eat.
D.
The Germ Theory Of Disease is a theory that microorganisms are the cause of many disease. Although it didn’t seem plausible at the beginning, it is now a major influence in modern medicine.

Rudolf Carl Virchow (1821-1902) German doctor.
He was one of the first people to describe “white blood” leukemia Also found social medicine
Robert Koch
Famous for the discovery of the anthrax. Identified microbe that caused “Anthrax” which was killing thousands of cows.
Florence Nightingale (1820-1910)
Wartime Nurse
Famous for her work in the military hospitals of the Crimea, Nightingale established nursing as a respectable profession for women. In 1860, she established the Nightingale Training School for nurses at St Thomas' Hospital in London.
Joseph Lister
He had explored the inflammation of wounds. At the Glasgow Royal Infirmary he put in charge of its new surgical building.
B. Plasma membrane: is the last wall of protection, capsule: is the layer that covers the cell, and pili: are the sensory tips on the cell.
C. His research led to the process of pasteurization of milk to kill viruses and harmful bacteria. The milk is not heated to the boiling point which would change the flavor, but is heated to a temperature sufficient to kill the bacteria which would cause it spoil easily or cause disease. It is then chilled and must be kept cold until used. He named the new science bacteriology and suggested a new theory, The Germ Theory of Disease. He believed that diseases were caused by germs attacking the body from the outside. The idea of immunization* with a weakened version of a disease was not new. As early as 1774 a vaccine for smallpox* had been discovered, and Edward Jenner before 1800 was vaccinating people against smallpox. He found that if he inoculated people with cowpox, they got the less severe disease which prevented them from getting smallpox.
D. The germ theory of disease is mostly about the diseases over time and how they can be prevented.
B.) 3 main components of the Cell Theory are:
1. All living things or organisms are made of cells and their products.
2. New cells are created by old cells dividing into two.
3. Cells are the basic building units of life.
C.) Louis Pasteur created a thing called "pasteurization" which kills bacteria and viruses that live in your milk. They still use this process today.
D.) The germ theory of disease is a theory that proposes that micro organisms are the cause of many diseases.
